Code is too large to fit STM8

[UsrnameTaken]

After running make I get this:

CC main.c
CC display.c
CC uart.c
CC eeprom.c
CC outputs.c
CC config.c
CC fixedpoint.c
CC parse.c
CC adc.c
LINK b3603.ihx
Code is too large, it is 8570 bytes
Makefile:12: commands for 'check_size' object failed
make: *** [check_size] error 1

What version of sdcc are you using? please show the output of sdcc -v

Mine is 3.4.3 and the code generated is 7915 bytes.

You can also use the command make SHELL='sh -x' to show the commands and make sure that you have the option --opt-code-size in there.

I am using v. 3.4.0 since newer version had some strange problem. SDCC : mcs51/z80/z180/r2k/r3ka/gbz80/tlcs90/ds390/pic16/pic14/TININative/ds400/hc08/s08/stm8 3.4.0 #8981 (Apr 5 2014) (Linux)

The code was downloaded and straight from this I tried to compile. Makefile has --opt-code-size in CFLAGS= but make SHELL='sh -x' shows: + grep ^CODE b3603.map+ head -n1

+ sed -e s/^.*=\s*\([0-9]\+\).*$/\1/ + CODESIZE=8570 + [ 8570 -gt 8192 ] + echo Code is too large, it is 8570 bytes > 8192 Code is too large, it is 8570 bytes > 8192 + exit 1 Makefile:12: commands for 'check_size' object failed make: *** [check_size] error 1

To see the command you need to first make clean and then rebuild with the shell option.

There is no real reason for the size difference other than the compiler. There are likely missing optimizations in your version and not much I can do about it directly.

If you want you can try a fork of this project that also tried to reduce size from https://github.com/swegener/b3603/tree/size-reduction

Thanks to you problem is solved. I couldn't find v. 3.4.3, but 3.5.0 works good with additional option. I've tried compiling reduced size version, but with 3.4.0 the result was worse, than regular.
